Introduction
The requirements defined in the present document have been selected to ensure an adequate level of compatibility with
other radio services. The levels, however, do not cover extreme cases, which may occur in any location but with a low
probability of occurrence.
The present document may not cover those cases where a potential source of interference which is producing
individually repeated transient phenomena or a continuous phenomenon is present, e.g. a radar or broadcast site in the
near vicinity. In such a case it may be necessary to use special protection applied to either the source of interference, or
the interfered part or both.
The present document does not contain any requirement, recommendation or information about the installation of the
LMES.

ETSI EN 301 444 V1.2.1 (2012-01)
The previous version [6] of this harmonized standard contained two sets of limits to provide a transition from
TBR 044 [4]. One set of limits (table 2a) was applicable up to 1 June 2002 and a more stringent set (table 2b) was
applicable after this date. The first set of limits (table 2a) has been removed in the present document since it is no longer
required. The second set of limits (table 2b) is retained for existing and legacy LMES and may continue to be used for
LMES that only operate in the original L-band allocation (sub-band 1 as defined in table 1a).
The determination of the parameters of the user earth stations using a given geo-stationary satellite for the protection of
the spectrum allocated to that satellite, is considered to be under the responsibility of the satellite operator or the
satellite network operators. Applicants for LMESs operating in satellite networks which provide radio navigation service
and/or other safety services should note that such satellite network operators may require testing in addition to the
present document to prove correct interworking in order to avoid the LMES causing harmful interference which
endangers the functioning of these services. References to these requirements will be listed in the Bibliography of the
present document as they become known.
The present document specifies a new set of emission requirements for LMESs that are capable of transmitting in the
frequency band from 1 668,0 MHz to 1 675,0 MHz. Following the WRC-03 decision to allocate to MSS the bands
1 518 MHz to 1 525 MHz (space to Earth) and 1 668 MHz to 1 675 MHz (Earth to space) and the conclusions of
WRC-07, the present document specifies the necessary requirements to harmonise the use of these extended frequency
bands by LMESs.
The present document treats the two parts of the L-band frequency allocation (as extended) as two sub-bands which
may be used separately or in any combination. The original L-band allocation is referenced in the present document as
"sub-band 1" and the extended L-band is referenced as "sub-band 2".
A new table 2c is added to the present document for LMESs that are capable of transmitting in any combination of
either or both of these sub-bands. The new table 2c is recommended for all new LMESs including LMES that can only
operate in sub-band 1.
The applicant may choose between tables 2b and 2c for new LMESs that are capable of transmitting in only the
sub-band 1. The applicant has to declare which alternative is used.

The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) Article 3.2
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present
document.

the 1 625,8 MHz to 1 661,2 MHz band, but outside the nominated bandwidth, shall not exceed the limits of table 3; and
the emission limits within the 1 667,3 MHz to 1 675,7 MHz frequency band shall not exceeded 74 dBpW in any
100 kHz measurement bandwidth.
NOTE 1: If an applicant declares to use table 2b for an LMES the same emission limit for the 1 667,3 MHz to
1 675,7 MHz frequency band is also defined in table 2b.

-
Unconditional: meaning that the requirement applies in all circumstances; or
-
Conditional: meaning that the requirement is dependent on the manufacturer having chosen to support
optional functionality defined within the schedule.
•
in the case of Conditional requirements, it associates the requirement with the particular optional service or
functionality;
•
it qualifies each test procedure to be either:
-
Essential: meaning that it is included with the Essential Radio Test Suite and therefore the requirement

NOTE:
Indicates whether the test specification forms part of the Essential Radio Test Suite (E) or
whether it is one of the Other Test Suite (O).
All tests whether "E" or "O" are relevant to the requirements. Rows designated "E" collectively make up
the Essential Radio Test Suite; those designated "O" make up the Other Test Suite; for those designated
"X" there is no test specified corresponding to the requirement. The completion of all tests classified "E"
as specified with satisfactory outcomes is a necessary condition for a presumption of conformity.
Compliance with requirements associated with tests classified "O" or "X" is a necessary condition for
presumption of conformity, although conformance with the requirement may be claimed by an equivalent
test or by manufacturer's assertion supported by appropriate entries in the technical construction file.
Clause Number
Identification of clause(s) defining the test specification in the present document unless
another document is referenced explicitly. Where no test is specified (that is, where the
previous field is "X") this field remains blank.
